Ipsilateral Alar Angle
An angle relating the two outer eyelid-hood endpoints to the nose-bottom landmark.
What is measured
The calculation
Interior angle: left outer eyelid hood → nose bottom → right outer eyelid hood

Why it matters
This summarizes a triangular relationship between the lateral eye region and the nose. Eye-region width and vertical nose placement both change the triangle.
- Lower: a narrower angle at the nose, from a taller triangle or closer outer eye points.
- Higher: a wider angle at the nose, from a shorter triangle or wider outer eye points.
Where the idea comes from
FaceIQ adaptation
This is a FaceIQ landmark-based description of facial shape. The linked research provides background on facial measurement or perception; it has not directly validated this exact formula or its score. [1]
A worked example
If the rays from the nose bottom to the two outer eyelid-hood points enclose 88°, the result is 88°. Moving the outer points farther apart widens that angle.
Example values explain the calculation. They are not a target range and are not measurements of the schematic above.

New “Golden” Ratios for Facial BeautyFour experiments varied eye spacing and eye-to-mouth distance in face images. Preferences depended on feature arrangement. The tested ratios and stimuli do not validate every FaceIQ measurement or a universal ideal.
